In addition to the usual chm Windows help file, YouTube movies and links to our web site, we have found it necessary to develop a comprehensive user guide to support our LITECAD application. Here is a link: http://www.plus.designcad.com.au/?q=node/217
Based on a survey of our users, we believe that the majority want help in the form of YouTube movies. We now minimize the amount of written material we generate and add movies to the YouTube stock. As at December 2014, we have >500 movies showing how our LITECAD.DLL product works - just search for gCADPlus in YouTube.
